“…Subjects related to core binders were also dealt with by the authors of article [3]. The aim of this work was to evaluate the parameters of core mixtures with various binder systems in terms of core collapse after casting and the obtained quality of castings reflecting surface requirements based on non-ferrous metal alloys.…”

“…the current trend towards greening production is looking for a suitable alternative in 'green' inorganic binders. although for many decades standard inorganic binders could not be compared with organic resins in terms of technological properties, new inorganic binder systems are currently being developed that can largely eliminate disadvantages, which include, in particular, significantly lower collapsibility and reclaimability, and lower mechanical strength values [20].…”

Technology of ProducTion of Mold filling MaTerial for SPecific PurPoSeSin The field of MeTallic foaM caSTing this paper describes the technology for the production of precursors (space holder material) used to form the complex internal structure of cast metal foam. the precursor material must exhibit sufficient refractoriness, resist contact with liquid metal and at the same time should exhibit good collapsibility after casting. With regard to the greening of foundry production, the focus of this paper was on materials that could exhibit the above properties and at the same time do not have a negative impact on the environment. In this paper, the technology for the production of spherical precursors from a self-hardening mixture with a geopolymer-based binder system is described and verified. the motivation for the choice of material and all the sub-steps of the process -molding into the core box, tumbling, including the necessary accompanying tests of the mechanical properties of the core mixture being verified -are described.

“…To address this problem, in recent years, the use of low-emission products, known as inorganic binders, has been proposed [4][5][6]. The most studied and used are realised by mixing sodium silicate or aluminium silicate with water, so the resulting emissions of hazardous and polluting compounds are strongly reduced [7]. Despite their great potential, nowadays, inorganic binders are used on an industrial scale exclusively in the manufacturing of non-ferrous castings, mainly in aluminium [8].…”

The foundry industry is responsible for the production of several potentially polluting and hazardous compounds. One of the major sources of pollution is the use of organic binders for the manufacturing of sand cores and sand moulds. To address this problem, in recent years, the use of low-emission products, known as inorganic binders, has been proposed. Their use in ferrous foundries, otherwise, is limited due to some problematic features that complicate their introduction in the manufacturing process, as often happens when a breakthrough innovation is introduced. In light of this, the aim of this work is to provide a Green Innovation Practice (GIP) to manage the introduction of green breakthrough innovations, as previously described, within an existing productive context. This practice was applied to better manage the experimental phase of the Green Casting Life Project, which aims to evaluate the possibility of using inorganic binders for the production of ferrous castings. After describing the state of the art of GIPs and their application in manufacturing contexts, the paper described the proposed GIP and its application to a real case consisting of testing inorganic binders in a ferrous foundry.
